Abstract

An intake manifold (2) for an internal combustion engine equipped with an exhaust gas recirculation (EGR) system capable of recirculation a part of the exhaust gas to the intake system, having a configuration capable of preventing oil contained in the blow-by gas supplied by a positive crankcase ventilation (PCV) system or the air supplied by a turbocharger from flowing into the EGR gas outlet (10) of the EGR system opened to the intake manifold (2). The EGR outlet (10) is formed in the upper section of the interior of the intake manifold (2) so that the flow of oil into the EGR gas outlet (10) is impeded.
